Our God is love: and all His saints. [Brotherly Love.] We have not been able to trace this hymn beyond Cotterill’s Selection, 1819, No. 129, where it is given in 4 stanzas of 4 lines, and headed,”For Christian Love.” It is not by Cotterill, and although sometimes attributed to Wilkinson, its authorship is unknown. It is in somewhat extensive use.
